I am using the XFCE desktop for Porteus and I want to create the save.dat container for saving my changes in the system. I open up the save file manager and choose the name for the file and destination (I chose the folder where Porteus is installed on the usb stick). Then I press Ok and a window pops up where it says "Processing now" Creating save.dat file.. and it is doing it for over half an hour already. The process bar is the same, at 0 percentage.

I am totally new to Linux and to Porteus, and very keen on using it, but is struggling with the .dat-container as well..

Your savefile will be at /tmp/savefile.dat and you MUST move it outside of the live file system.

I too, have been trying to put my .dat-container in the Porteus-directory, but if I cant do that, can I put it in the root of the USB stick ie.?
And how do I type the correct destination into the .cfg file?

I have noticed when Porteus boots the screen says "using Porteus data from /mnt/sdb/Porteus."
In order to get the .dat container the "easy" way, I figured I would put my .dat-container in the Porteus-directory, therefore typing the destination for the save-file destination as "/mnt/sdb/Porteus/name.dat".
But Porteus cant find the .dat-container, so something is obviously wrong.

The easiest way to create the save.dat file is to use Porteus's Save File manager. Found via menu > System Tools. Saving it to the flash drive's porteus folder is fine but do note that Linux is case sensitive, thus Porteus and porteus are two different names so maybe saving it to the flash drive's root might be a better place to start. And no need to get to get carried away with size, start with 512MB and you should be fine. I have one system with one half that.

At some point you will hear about the flash drive's UUID but for the moment lets concentrate on the save.dat file. Once you have created it, and located it you need to add it to the porteus.cfg file. Something like this:
